摘要:

光晶格中的原子一直是AMO研究的热点,近年来人们对该系统的短程和长程相干性及其在量子信息处理中的应用进行了大量的研究。在这里,我们证明了第一次完整的测定的量子相空间分布的$^{85}Rb$原子在这样的晶格中,包括一个负的维格纳函数的原子在一个倒置的状态。

英文摘要:

Atoms trapped in optical lattice have long been a system of interest in the AMO community, and in recent years much study has been devoted to both short- and long-range coherence in this system, as well as to its possible applications to quantum information processing. Here we demonstrate for the first time complete determination of the quantum phase space distributions for an ensemble of $^{85}Rb$ atoms in such a lattice, including a negative Wigner function for atoms in an inverted state.
